Preselector

A preselector is a name for an electronic device that connects between a radio antenna and a radio receiver. The preselector is an adjustable band-pass filter that blocks troublesome out-of-tune frequencies from passing through from the antenna into the radio receiver or preamplifier that otherwise would be directly connected to the antenna.
